T 0 all whom it may concern:

Be it known ilmfiLEBIAXUEL MONTEC-INO, a citizen of the United States, and a resident of Raceland, in the parish of Lafourche and State of Lou1s1ana,.have made certain new and useful Improvements in Apparatus for Filtering Sugar-Cane Juices, of which the following is a specification.

My invention is an improvement in apparatus for filtering sugar cane juice, and con-' sists in certain novel constructions and combinations of parts, hereinafter described and claimed. q The object of the invention is to provide an apparatus of the character s ecified which will eliminate a maximum 0' impurities from the juice, and which will pro duce a. better quality of-sugar from the same tank or rat B, within which is a filter box having open sides and an open bottom, and

of lesser size than the tank, so that there is a space l'ietween each Wall of the bOX and the corresponding wall of the tank. The

said box is formed of five open frames C,-

joined at their edges to form an open top box, into which the trough A dellvers. Each of the frames is cove-red with two layers of wire gauze O secured to the frame in any suitable manner, and the tank B is' provided with a false bottom E upon which the box rests. The false bottom is supported by bars F, one arranged near each end of the tank and in the space between each side wall of the box and the cor-re spending wall of the tank, is a filtering pad G, the said ad being continuous,1'and entirely encircing the box. The pad -extendsfrom the top to the bottom of the tank, but thr space between the floor and the false floor is vacantas shown.

A distributing trough H,leads from the tank B to a second tank or vat I, the vat I being at a lower level than the tank B, and the troughextends the full length of the vat. The tank B is provided with an 0 ening in its bottom delivering into thetrbugh, and the trough is provided with open ngs throughout its length delivering to th' "vet I. The vat I is filled with filtering fray es,

"K arranged in superposed series, prefer ably five frames in each series, and the height of the side wall of the vat issuch that the edge of the upper frame is flush with the edge of the wall. Only the two series at the end of the vat remote from the tankare shown, and the top frame of each series is removed. Thesize of the frames with respect to the vat is such that the entire cubical contents of yet is occupied by the frames, as for instance ,in a vat l5x10x4 inside measure, there would be 50 frames 5x3 outside measure, and the bottom frame K i's of lesser length than the upper frames, in'order that the juice may readily pass out at the bottom. '.Each of the frames K is open, and the bottom is covered with a la er M of Wire! gauze of suitable mesh, an with a layer N of hemp or ag'aveor other suitable material, the layer N being above the layer M. .Each of the.

:trames on each side of the vat has its outer end in contact with the side wall, and on ac- -coun t' of the lower frame-being of lesser length a passage Q is formed the entire length of the vatw v The above described apparatus. is interposed between the mill and the evaporator, and preferably a portion of the molasses of each strike is passed from the centrifugal to the tank B and caused to undergo another filtration with the new juice. The tank B may also be arranged infront of the evaporator or resting tank,to filter the material passing into the tank, whereby toelnninate the gum from the syrupin orderto obtain a larger amount of sugar per ton. Y v

\Yith the improved apparatus interposed as' stated, the necessity of skimming is dispensed with, since tliejuice.v is filtered beforecooking, nd since there is no pressure.

the coloring i atter of the cane will not erpress to discolor the juice. ,If desired sulfor may be used to discolorize the juice when the juic leaves the vat.

I claim a 1. Anapparatus of-the character specified, comprising a tank havin an open top, a false bottom in the tank an spaced above the true bottom, a box resting on thefalse bottom, said box having open sides and an open bottom, a double layer of wire gauze covering saidsides and bottom, a filter pad encircling the side walls of the box and between said walls-and the Walls of the tank,

a distributing trough below the tank and to- .which it delivers, a vat, saidtrough extendl ing the full length of the vat at approxifing said sides an mately its'longitudinal center, and having openings for delivering the juice to the vat, l

and a plurality of filter frames in the vat, said frames being arranged in superposed series, the series being arranged in rows one on each side of the trough, and occupying the entire space within the vat, each of said frames having a bottom composed of a layer of wire gauze and a layer of hemp oraag'ave, the bottom frame of each series being of lesser length than the upper frames and spaced apart frointhe corresponding frame on the opposite side of the vat to form a passage at the center of the-vat.

2. An apparatus of the character specified, comprising a 'tankhavingan open top, a false bottom 1n the tank and spaced above the true bottom, a box resting on the false bottom, said box having open sides and an open bottom, a la er of wire uze coverbottom, a fi ter pad encircling the side walls of the box and between said. walls and the walls of the tank,

a distributing trough below the tank and to which it delivers, a vat, said trough extending the full length of the vat at approximately its longitudinal center, and having openings for delivering the juice to the vat,

and a plurality of filter frames in the vat,

said frames being arranged in superposed series, the series being arranged in rows one on each side of the trough, and occu yin the entire space within the vat, each 0 sai frames having a bottom composed of a layer of wire gauze and alayer of hemp or agave, the bottom frame of each series being of lesser length than the upper frames and spaced apart from the corresponding frame "on'the opposite side of the vat 'to form a passage at the center of the vat'. I

3. In'an apparatus of the character specified, a tank, a false bottom in the tank and I spaced above the truebottom, a box" having 0 n sides and an open bottom resting on e ,false bottom, a covering of wire-gauze oncach'side of the bottom, the sides of the box being spaced apart from the; sides of the tank, and a filter pad between each :wall "of the boxand the corresponding wall of the tank;

comprising a ranged with their ends abutting the en 4. In an apparatus ofthe character speci 5. In an apparatus of the character specified, a tank and a box having perforate sides and a perforate bottom supported in the tank with the walls and bottom of the box spaced apart from the walls and bottom of the tank, and a filter pad between the corresponding walls of the box and tank.
